Which of the following is NOT a symptom of fecal impaction?

C is the correct answer because increased appetite is not typically associated with fecal impaction. In fact, individuals experiencing fecal impaction often face a decrease in appetite due to discomfort and the body's reaction to the blockage. Other symptoms, such as decreased muscle tone in the lower bowel, a constant feeling of needing to have a bowel movement, and abdominal discomfort and nausea, are commonly observed as the body tries to manage the effects of the impaction. These signs indicate that the gastrointestinal system is under stress, and increased appetite would likely not be a manifestation in such a condition.
